Problems solved by technology

[0004] This type of solution disadvantageously has increased requirements in terms of space in most cases
In addition, battery cells are usually only cooled from one side of the battery cell and are therefore not sufficiently cooled
In addition, the balancing of tolerances and the sealing of battery modules can also be problematic

Embodiment Construction

[0029] figure 1 Shows a sectional view of a battery pack 1 according to the invention for a hybrid or electric vehicle in a first embodiment; here the battery pack 1 has a plurality of battery elements 2 and a cooling device 3 with a plurality of cooling elements 4. figure 1 Only a part of the battery pack 1 is shown in FIG. It goes without saying that the accumulator assembly 1 can also have further battery cells 2 and other cooling elements 4, and further structural elements, such as fluid distributors through which the flow of cooling fluid can flow, or fluid flow channels through which the flow of cooling fluid can flow. collector, or tensioner. The individual cooling elements 4 are arranged here between the battery cells 2 and are fixed together with the power supply units in the stacking direction 5 in order to form a battery block 6 . The cooling element 4 in the first embodiment of the accumulator assembly 1 is formed by a compressible porous intermediate insert 7 h...

Abstract

The invention relates to an accumulator arrangement for a hybrid or electric vehicle. The battery arrangement has a plurality of battery cells (2) with opposing support surfaces, wherein the battery cells are stacked in the stacking direction to face one another by the support surfaces so as to form a battery block (6). The accumulator arrangement also has a cooling device with a plurality of cooling elements through which a cooling fluid can flow and which are arranged between the adjacent battery cells (2) and braced with them in the stacking direction. According to the invention, each cooling element has a compressible and porous intermediate insert with a plurality of pores through which the cooling fluid can flow or is formed by the intermediate insert, the intermediate insert being arranged between the respective adjacent battery cells and being connected to the battery cells in a heat-transferring manner.

Description

technical field [0001] The invention relates to a battery pack for a hybrid or electric vehicle according to the preamble of claim 1 . Background technique [0002] A battery pack or traction battery, respectively, for a hybrid vehicle or an electric vehicle usually has a plurality of individual battery cells which are combined to form a battery module. The individual battery cells in the individual battery modules are here held together by tensioning devices. In the case of battery packs, by virtue of the unstable shape of the tensioning device, the tensioning device must additionally be held together by suitable fastening or suitable components, respectively. Furthermore, the individual battery cells in the battery module must be cooled, wherein in particular it is necessary to improve the heat dissipation between the individual battery cells supported on one another. [0003] For example, in the case of battery packs, an auxiliary frame of plastic material can be used t...
